So you're going to focus on one point out of four? These games and TV (including the reporting of a shooting every other week) have completely desensitized America. While we may have crossed the point of no return, we can attempt to do some damage control. And no, blaming a...MILITARY-GRADE TOOL OF ...

You can make the invulnerability a bit less convenient.
Personally I feel bosses should be a noticeable difficulty spike right at the end of the level. D1L7 definitely captured this, while D2L4 just had a big robot with more health that just happens to teleport and start the countdown.

They are separate bosses with separate HP. Parallax never anticipated level developers using multiple bosses, and thus when one dies the "boss is dead" function is called - which acts on all bots that have the boss flag set. It runs the "valid boss arena" algorithm from the first (or last?) boss it ...

Be careful about what tracks you assign levels 2 thru 7 - they'll be applied to the 6 secret levels in that order. I don't personally think D1L8 sounds too Quartzon-y
(That track gets applied to Quartzon Planetary Vault based on the current scheme)

Personally (from experience) I think it could be a bit larger. Especially since it's on Brimspark. While we're on the topic of size and Brimspark levels, IMO The Cauldron should be larger (if you can tone down the cube count in that one room :P). If that doesn't seem to be possible, then I'd recomme...

Unopenable secrets? - The one in the spiral is opened by flying further down the spiral - The one by the blue door is opened by flying into the main chamber I can't think of any others... Edit: The only door that cannot be opened legitimately is the start hatch, and it's never meant to. There are no...

Here's Coolyard: https://drive.google.com/file/d/1CrMSztO9sxxb3uVKLBFaIeQJEYkNlah0/view?usp=sharing Small detailing upgrades along with a slight tweak to the fire escape. The level will look noticably smaller on the automap, but that's due to the fact that I wound up "folding in" a chunk of the leve...

Make sure: - The sides are actually adjacent (look at the cubes; if the cube next the cube you're trying to align is not the cube with the other side, the sides aren't adjacent). There is a fix in using the "Align All Sides" checkbox, but you have to be careful as weird stuff can happen (including t...

I've discovered that leaving "classic lighting" unchecked in DLE concentrates the lighting more around the sources rather than distributing it. Combine that with a lower "render distance", and you can get some good atmosphere.

The logic behind "Metacave" is that it takes the traditional role of being the planet the mine is on (Lunar Outpost, Metacave Weapons Research), and I liked the texturing scheme - hence making a Metacave-textured level makes sense on the planet Metacave.
